Description
Technical field
The utility model belongs to field of cable technology, particularly relates to a kind of copper core embossing copper sheath inorganic mineral insulation fireproof cable.
Background technology
Along with Urbanization Process is constantly accelerated, population is more and more denser and concentrate, and high buildings and large mansions are not only much but also higher, and people more and more pay attention to building firesafety, more and more higher to the technical performance level requirement of building fireproof cable, traditional fire-resisting cable can not adapt to new requirement.Traditional fire-resisting cable only has a technical performance index, is namely fire-resistant 750 DEG C merely, keeps the integrality of electric wiring, guarantee safe power transmission in 90 minutes; When this is with fire-fighting fire extinguishing, thermal-flame, water drench and the actual conditions of mechanical shock differ greatly.After 2004, multiple cable producer develops magnesium oxide insulated copper sheath cable in succession.Because the structure of magnesium oxide insulated copper sheath limit, it is short that it manufactures length, many at use cable line center tap, bendability is poor, constructional difficulties.In addition, the easy moisture absorption of magnesium oxide, after the moisture absorption, insulation resistance obviously declines, and affects cable serviceability.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of copper core embossing copper sheath inorganic mineral insulation fireproof cable that can meet for electrical length needs.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises cable core, cable core is enclosed with cable core insulating case, its structural feature insulating case outer surface is enclosed with embossing copper sheath, is disposed with tinned copper wire from the inside to the outside and weaves cylinder, Teflon polymeric dielectric layer, tinned copper wire woven shield between cable core and cable core insulating case.
As a kind of preferred version, embossing copper sheath described in the utility model adopts dephosphorization copper belt.
As another kind of preferred version, cable core described in the utility model is made up of many copper conductors, and every root copper conductor is enclosed with conductor insulation cover.
As another kind of preferred version, copper conductor described in the utility model is made up of many stranded soft copper cores.
As another kind of preferred version, between conductor insulation cover described in the utility model, be filled with inorganic glass fiber silk.
As another kind of preferred version, the count of tinned copper wire woven shield described in the utility model is not less than 80%.
Secondly, cable core insulating case described in the utility model and conductor insulation cover all adopt Inorganic synthese mica tape.
In addition, Inorganic synthese mica tape described in the utility model is five layers, five layers of overlapping wrapped setting of Inorganic synthese mica tape.
The utility model beneficial effect.
The utility model embossing copper sheath can meet for electrical length needs, and no matter be single core or multicore cable, every root continuous length can reach more than 1000m; Shielding properties is superior, can not produce interference under the shielding of copper sheath to the information of signal, control cables transmission; Security performance is good, and copper sheath is excellent conductor, is best PE line, substantially increases ground protection sensitivity and reliability.
The utility model Teflon polymeric dielectric layer heatproof can reach 200 DEG C, and fail safe is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection range is not only confined to the statement of following content.
Fig. 1 is the utility model structural representation.
In figure, 1 be embossing copper sheath, 2 for cable core insulating case, 3 for conductor insulation cover, 4 for copper conductor, 5 for tinned copper wire woven shield, 6 for Teflon polymeric dielectric layer, 7 for tinned copper wire weave cylinder.
Embodiment
As shown in the figure, the utility model comprises cable core, cable core is enclosed with cable core insulating case 2, insulating case outer surface is enclosed with embossing copper sheath 1, is disposed with tinned copper wire from the inside to the outside and weaves cylinder 7, Teflon polymeric dielectric layer 6, tinned copper wire woven shield 5 between cable core and cable core insulating case 2.Embossing copper sheath 1 is by circular argon arc welding continuous rolling.
Described embossing copper sheath 1 adopts dephosphorization copper belt.Dephosphorization copper belt good waterproof performance, good airproof performance, can be used as submerged cable and use.
The count of described tinned copper wire woven shield is not less than 80%.
Described cable core is made up of many copper conductors 4, every root copper conductor 4 is enclosed with conductor insulation cover 3.
Described copper conductor 4 is made up of many stranded soft copper cores.The conductor adopting many stranded soft copper cores to form has flexibility, and cable can coil on cable hank, and its bending radius≤20D(D is the outside diameter of cable), solve the problem of magnesium oxide insulated copper sheath cable bend difference.
Inorganic glass fiber silk is filled with between described conductor insulation cover 3.
Described cable core insulating case 2 and conductor insulation cover 3 all adopt Inorganic synthese mica tape.Inorganic synthese mica tape has good insulating properties, thermal endurance and chemical resistance, heatproof: 1100 DEG C, fusing point: 1375 DEG C, and cable can not burn in a fire, also can not melt in burning.
Described Inorganic synthese mica tape is five layers, five layers of overlapping wrapped setting of Inorganic synthese mica tape.
Through experiment proved utility model resistance to baked wheaten cake, cable seal is good, Stability Analysis of Structures is fastening is not afraid of mechanical shock.Its Technique performance parameter: 1, fire-resistant merely: 950 DEG C, 180min; 2, the fire-resistant pouring that adds water: 650 DEG C, burning limit, 15 minutes back water drenches 15 minutes; 3, fire-resistantly add mechanical shock: 950 DEG C, vibrations in 15 minutes keep electric wiring integralities 30 times.Therefore, the utility model can safe power transmission in case of fire, guarantees that fire-fighting equipment normally runs.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection range of the present utility model as long as meet.
